Building A Distributed Build System at Google Scale (StrangeLoop 2016)

Aysylu Greenberg

It's hard to imagine a modern developer workflow without a sufficiently advanced build system: Make, Gradle, Maven, Rake, and many others. In this talk, we'll discuss the evolution of build systems that leads to distributed build systems. Then, we'll dive into how we can build a scalable system that is fast and resilient, with examples from Google. We'll conclude with the discussion of general challenges of migrating systems from one architecture to another.

Microservices in Golang

Mo'ath Qasim

Every single developer heard this say more than one time during his professional career, 'KIS' which means 'Keep It Simple', however with the excessive evolvement of the web computing and the continues rise of the distributed systems, the complexity of the systems architecture increases. Building a server enterprise application which is highly scalable with high and reliable availability in addition to great performance which consists of set of independent deployable oriented services can be achieved by Microservice architecture. This session introduces briefly what is the Microservice Architecture and how to build it using one of the most popular server programming languages which is called Go or Golang.

Code review vs pull request

Bryan Liu

Presented at Open Source 101 2022 Presented by Victoria Dye, GitHub Abstract: For many developers, a Git commit is just a step in their source control ritual: an arbitrary save point at the end of a work day, the Nth attempt at finding the right syntax for a CI workflow, or a satisfying bookend to fixing a bug. But commits provide far more than that: they tell the story of how each line of code was created and modified. Despite their unassuming nature, they are one of the best ways to answer the question "why did I write that?" The story told by a repository's commit history is both richer and more essential in the open source world. Well-structured commits can guide you in the implementation of a new feature, break down complex reviews into easily-digestible increments, and provide an invaluable resource to future contributors hoping to extend functionality or find the root cause of a bug. This talk will show how high-quality commit organization can benefit you now and in the future. First, we will introduce strategies and tools to tell a clear story through commits. Later, we will demonstrate how to use an informative commit history while reviewing code and investigating bugs.

Bootiful Development with Spring Boot and React - RWX 2017

Matt Raible

To simplify development and deployment, you want everything in the same artifact, so you put your React app “inside” your Spring Boot app, right? But what if you could create your React app as a standalone app and make cross-origin requests to your API? A client app that can point to any server makes it easy to test your current client code against other servers (e.g. test, staging, production). This session shows how to develop with Java 8, Spring Boot, React, and TypeScript. You’ll learn how to create REST endpoints with Spring MVC, configure Spring Boot to allow CORS, and create an React app to display its data. If time allows we’ll cover authentication with OpenID Connect and deployment to Cloud Foundry.

Why you should embrace Gradle and ditch Maven

GijsLeussink

Abstract: Still using Maven as a build tool in your projects? If so, are you using it because you think it is a great tool, or just because you’ve always done it this way? Within 15 minutes we’ll share with you the reasons that made us ditch Maven and fall in love with our build tool again. Be aware though, after you’ve visited this quickie there is a big chance you’ll find yourself migrating all your projects tonight. Luckily, this is easier than you might think. Talk (quickie) of 15 minutes on 8th November 2018 at J-Fall 2018, the annual Dutch Java User Group (NLJUG) conference.

Jakarta EE! The future of enterprise application behind the myths. Most enterprises continue running their Application in a JEE Server. We realize that there are among of code that is not evolving. Throughout this talk, we are showing you by example some real-world experiences of moving forward Applications running JEE 5 & 7 to Jakarta EE 10. At the end of this session, you are going to understand the pitfalls and put away the concerns of updating and evolving your enterprise applications.

Ambassador Labs

Every software development cycle is rife with inefficiency. Seasoned devs know the pain of getting access to essential remote systems, waiting for tests to run (and then fail), or debugging with only log files. This talk teaches you how to best leverage Kubernetes, remote infrastructure and related tooling to create a dev cycle that maximizes velocity and minimizes developer friction and frustration. Using tools such as Kubernetes, Docker and Telepresence, I will walk attendees through several advanced techniques that can be used to produce an effective developer experience and optimized dev loop. The goal of this is to eliminate many sources of frustrating inefficiency and reduce cycle time between releases. I will demonstrate how to incrementally adopt some of these techniques and how to approach introducing new and unfamiliar technology and techniques to skeptical dev teams.

Free The Enterprise With Ruby & Master Your Own Domain

Ken Collins

On the heals of Luis Lavena's RailsConf talk "Infiltrating Ruby Onto The Enterprise Death Star Using Guerilla Tactics" comes a local and frank talk about the current state of Open Source Software (OSS) participation from Windows developers. Learn what OSS is, what motivates its contributors, and how OSS can make you a stronger developer. Be prepared to fall in love with writing software again! We will start off with a 101 introduction to both the Ruby programming language and the Ruby on Rails web application framework. You will learn about ActiveRecord, a powerful ORM that maps rich objects to your databases, and the latest components to use it with SQL Server. As a Rails core contributor and author of the SQL Server stack, I will give you a modern insight into both that will allow you to leverage your legacy data with Ruby. Lastly, I will review the bleeding edge tools being actively created for Windows developers to ease the transition to Ruby, Rails and OSS from a POSIX driven world. Many things have changed. It is time to learn and perform some occupational maintenance.

Scaling Up Lookout

Lookout

Scaling Up Lookout was originally presented at Lookout's Scaling for Mobile event on July 25, 2013. R. Tyler Croy is a Senior Software Engineer at Lookout, Inc. Lookout has grown immensely in the last year. We've doubled the size of the company—added more than 80 engineers to the team, support 45+ million users, have over 1000 machines in production, see over 125,000 QPS and more than 2.6 billion requests/month. Our analysts use Hadoop, Hive, and MySQL to interactively manipulate multibillion row tables. With that, there are bound to be some growing pains and lessons learned.

Matt Greenwood & Scott Draves - The Polyglot Beaker Notebook

PyData

The Beaker Notebook is a new open source tool for collaborative data science. Like IPython, Beaker uses a notebook-based metaphor for idea flow. However, Beaker was designed to be polyglot from the ground up. That is, a single notebook may contain cells from multiple different languages that communicate with one another through a unique feature called autotranslation. You can set a variable in a Python cell and then read that variable in a subsequent R cell, and everything just works – magically. Beaker comes with built-in support for Python, R, Groovy, Julia, and Javascript. In addition, Beaker also supports multiple kinds of cells for text, like HTML, LaTeX, Markdown, and our own visualization library that allows for the plotting of large data sets. This talk will motivate the design, review the architecture, and include a live demo of Beaker in action.

In today's increasing business need for more deploys, continuous testing, and better quality code, one thing that is not explicitly discussed is a strategy for how software teams should collaborate across their company. Before you invest all your time and energy into Continuous Integration or Continuous Delivery, make sure you have a solid foundation of Collaborative Development. In this talk, we'll look at some collaboration patterns that have had success, why they're important, and how you can adopt these patterns within your own software development teams to build software better tomorrow.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Search and Society: Reimagining Information Access for Radical Futures

Bhaskar Mitra

The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024

Tobias Schneck

As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other? Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neuro-symbolic is not enough, we need neuro-*semantic*

Frank van Harmelen

Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”. All of this illustrated with link prediction over knowledge graphs, but the argument is general.
